Hi, some time ago I was reflecting on how to boost performance on a Pentium Pro 200 MHz with 128MB RAM. I concluded that today's programming language and -style suffers from needless copying of data (not to talk about needless calling of code), making the relatively fast CPU cache quite useless. As a proof on concept I wrote a sample program that does very aggressive data sharing (kind of "copy on write"). The performance is really great (I did unpack MIME messages): It's about a factor of 1000 faster than PINE. However: Data inter-dependencies are terrible, and it's a maintenance pain. Performance sample (on a P4 2.8GHz meanwhile): base64-decoding 9219kB (includes reading the source (most likely cached, however) and writing the output): 0.161s (elapsed! time (wall time)) Now for XML... ;-) Regards, Ulrich --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
